What is a Memorandum of Understanding (MoU)?

A Memorandum of Understanding (MoU) is a document that sets out the key terms and intentions of two or more parties before they enter into a formal, legally binding agreement. In mergers and acquisitions, it helps buyers and sellers align on the main points of a potential deal before committing to detailed negotiations.

An MoU creates a shared understanding that guides the next stages of the process.

What is a Memorandum of Understanding?

In an M&A context, an MoU outlines the proposed structure of a deal at an early stage. It captures the commercial intent of both parties and provides a framework for moving forward.

While most of the document is non-binding, certain clauses may carry legal weight, so it is essential to draft it carefully.

Why use an MoU in M&A?

An MoU helps reduce uncertainty at the start of a transaction. It allows both parties to test whether they are aligned before investing time and resources into due diligence and legal work.

It also creates a clear reference point that advisers, lawyers and internal teams can use as the deal progresses.

What does an MoU typically include?

An MoU sets out the headline terms of the proposed transaction, such as:

  • The structure of the deal and what is being acquired
  • An indicative price or valuation range
  • Key milestones and a proposed timeline
  • Roles and responsibilities during the process
  • Any conditions that must be met before proceeding

These points are not final, but they provide direction for negotiations.

Binding vs non-binding elements

One of the most important aspects of an MoU is understanding which parts are legally binding.

Element

Typical status

Purpose

Commercial terms (price, structure)

Non-binding

Outlines intentions and guide negotiations

Confidentiality

Binding

Protects sensitive information shared during discussions

Exclusivity

Binding (if included)

Prevents the seller from negotiating with other parties

Governing law

Binding

Defines how disputes will be handled

How an MoU fits into the M&A process

The MoU sits between initial discussions and formal agreements. It usually follows a non-disclosure agreement and comes before detailed due diligence and definitive contracts.

After signing an MoU, the parties typically:

  • Begin due diligence to validate assumptions
  • Refine valuation and deal structure
  • Draft and negotiate final agreements

Benefits of using an MoU

Using an MoU can improve the efficiency of a deal process:

  • It aligns expectations early and reduces misunderstandings
  • It speeds up negotiations by setting a clear starting point
  • It helps advisers and stakeholders work from a shared framework

This can be especially valuable in competitive or time-sensitive transactions.

Risks and challenges

Despite its usefulness, an MoU can create issues if not handled carefully:

  • Ambiguous wording can lead to disputes later
  • Parties may assume terms are agreed when they are still subject to change
  • Binding clauses may create obligations that were not fully considered

The role of due diligence after an MoU

Once the MoU is agreed, the focus shifts to due diligence. At this stage, the buyer tests the assumptions set out in the document by reviewing financial, legal and operational information.

If issues arise, the parties may renegotiate terms or adjust the structure of the deal before moving to final agreements.
